Evelyn’s monthly income is $1150 and her savings is $345. Find savings to expenses ratio.

Savings to expenses ratio is 3:7

Solution

Evelyn's Income = $1150

Savings = $345

Expenses = 1150 - 345 = 805

∴ savings to expenses ratio = 345:805 = 3:7

Savings = $345

Expenses = 1150 - 345 = 805

∴ savings to expenses ratio = 345:805 = 3:7

2

Out of 176 students in a class, 32 are boys. Find boys to girls ratio.

Boys to girls ratio is 2:9

Solution

Total Number of students = 176

boys = 32

girls = 176 - 32 = 144

∴ Boys to girls ratio = 32:144 = 2:9

boys = 32

girls = 176 - 32 = 144

∴ Boys to girls ratio = 32:144 = 2:9

3

Length and breadth of a rectangular field are 216 feet and 54 feet respectively. Find the ratio of length to breadth of the field.

Length to breadth ratio is 4:1

Solution

Length of a rectangular field = 216

breadth of a rectangular field = 54

∴ Length to breadth ratio = 216:54 = 4:1

breadth of a rectangular field = 54

∴ Length to breadth ratio = 216:54 = 4:1

4

Out of 39 students in a class, 6 prefer football, 24 prefer baseball and remaining like tennis. Find the ratio of number of students who prefer football to number of students who prefer tennis.

Number of students who prefer football to number of students who prefer tennis ratio is 2:3

Solution

Total Number of students = 39

Number of students prefer football = 6

Number of students prefer baseball = 24

Number of students prefer tennis =39 - (6 + 24) = 9

∴ Number of students who prefer football to number of students who prefer tennis ratio = 6:9 = 2:3

Number of students prefer football = 6

Number of students prefer baseball = 24

Number of students prefer tennis =39 - (6 + 24) = 9

∴ Number of students who prefer football to number of students who prefer tennis ratio = 6:9 = 2:3

5

There are 50 teachers in a school of 1180 students. Find number of teachers to number of students ratio.

number of teachers to number of students ratio is 5:118

Solution

Total Number of teachers = 50

Total Number of students = 1180

∴ Number of teachers to number of students ratio = 50:1180 = 5:118

Total Number of students = 1180

∴ Number of teachers to number of students ratio = 50:1180 = 5:118

6

In a city of 7940 people, 2320 are government employees and the remaining are self-employed. Find government employees to self-employed ratio.

Number of Government employees = $2320

Self employed = 7940 - 2320 = 5620

∴ Government employees to self-employed ratio = 2320:5620 = 116:281

Number of Government employees = $2320

Self employed = 7940 - 2320 = 5620

∴ Government employees to self-employed ratio = 2320:5620 = 116:281
